      A patch to give a better overview of the userland application stack usage, · 3204de64
      Stefani Seibold authored
      especially for embedded linux.
      
      Currently you are only able to dump the main process/thread stack usage
      which is showed in /proc/pid/status by the "VmStk" Value.  But you get no
      information about the consumed stack memory of the the threads.
      
      There is an enhancement in the /proc/<pid>/{task/*,}/*maps and which marks
      the vm mapping where the thread stack pointer reside with "[thread stack
      xxxxxxxx]".  xxxxxxxx is the maximum size of stack.  This is a value
      information, because libpthread doesn't set the start of the stack to the
      top of the mapped area, depending of the pthread usage.
      
      A sample output of /proc/<pid>/task/<tid>/maps looks like:
      
      08048000-08049000 r-xp 00000000 03:00 8312       /opt/z
      08049000-0804a000 rw-p 00001000 03:00 8312       /opt/z
      0804a000-0806b000 rw-p 00000000 00:00 0          [heap]
      a7d12000-a7d13000 ---p 00000000 00:00 0
      a7d13000-a7f13000 rw-p 00000000 00:00 0          [thread stack: 001ff4b4]
      a7f13000-a7f14000 ---p 00000000 00:00 0
      a7f14000-a7f36000 rw-p 00000000 00:00 0
      a7f36000-a8069000 r-xp 00000000 03:00 4222       /lib/libc.so.6
      a8069000-a806b000 r--p 00133000 03:00 4222       /lib/libc.so.6
      a806b000-a806c000 rw-p 00135000 03:00 4222       /lib/libc.so.6
      a806c000-a806f000 rw-p 00000000 00:00 0
      a806f000-a8083000 r-xp 00000000 03:00 14462      /lib/libpthread.so.0
      a8083000-a8084000 r--p 00013000 03:00 14462      /lib/libpthread.so.0
      a8084000-a8085000 rw-p 00014000 03:00 14462      /lib/libpthread.so.0
      a8085000-a8088000 rw-p 00000000 00:00 0
      a8088000-a80a4000 r-xp 00000000 03:00 8317       /lib/ld-linux.so.2
      a80a4000-a80a5000 r--p 0001b000 03:00 8317       /lib/ld-linux.so.2
      a80a5000-a80a6000 rw-p 0001c000 03:00 8317       /lib/ld-linux.so.2
      afaf5000-afb0a000 rw-p 00000000 00:00 0          [stack]
      ffffe000-fffff000 r-xp 00000000 00:00 0          [vdso]
      
      
      Also there is a new entry "stack usage" in /proc/<pid>/{task/*,}/status
      which will you give the current stack usage in kb.
      
      A sample output of /proc/self/status looks like:
      
      Name:	cat
      State:	R (running)
      Tgid:	507
      Pid:	507
      .
      .
      .
      CapBnd:	fffffffffffffeff
      voluntary_ctxt_switches:	0
      nonvoluntary_ctxt_switches:	0
      Stack usage:	12 kB
      
      I also fixed stack base address in /proc/<pid>/{task/*,}/stat to the base
      address of the associated thread stack and not the one of the main
      process.  This makes more sense.

      Enable the coretemp driver on an Intel Atom. · 62c54ac4
      Michael Riepe authored
      I'm not sure if the readings are correct, however - on my 330, the driver
      reports values between 27 and 41 °C (with core1 being about 8°C hotter
      than core0, given the same load).  Maybe the maximum temperature of 100 °C
      is wrong for Atom CPUs.
